Is it permissible for a father to act on behalf of his son in concluding the latter's marriage contract, if both couple agree
and two witnesses testify to this?
It is permissible for a father to conclude the marriage contract on behalf of his son if the latter - who has to be of age - entrusts him to be the Wakil (legally accountable person who acts on behalf of another for a specific permissible matter). The marriage contract is valid if it fulfills all the required conditions and essential elements and has no impediments. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
